The actions of an Edmonton teenager may have saved a man’s life.

On Tuesday evening, Emily Devlin and her friends were downtown, outside the George Spady Centre, handing out food to the homeless when she noticed a man stick a needle in his arm.

The 16-year-old kept her distance but said soon after he used the suspected drug he started moaning — Devlin thinks he overdosed.

Feeling uneasy, the teens left, but Devlin said something nagged at her to go back.

“I’ve got to make sure he’s OK,” Devlin said.

“I don’t want to just leave someone there. I don’t want him to die.”

On the drive back, the teens called 911.

“I pulled into the parking lot so fast,” Devlin said, “almost like I was the one driving the ambulance.”

Devlin said no one was helping the man. When she lifted the blankets off of him, his hands were blue. She checked his pulse — he wasn’t breathing.

“That was quite terrifying.”

Devlin said she started chest compressions and tried to wake the man. Finally, she said she heard him moan and he appeared to vomit white foam.

Devlin said she then saw someone was being let in the George Spady building. She ran up and asked if there was a naloxone kit inside.
